The AirTAC GFR600C20ANT AirTAC Filter Regulator NPT 3/4 in is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600C20ANT is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration has 3/4 in NPT ports, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and an aluminium alloy bowl. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). No gauge is fitted with this code, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) element option, PT / G / NPT threads, and gauge or no-gauge variants. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Clean, regulated air feeding tool clamps, tool changers and actuated fixtures on a machining centre, with the automatic drain keeping condensate out of the valves between shifts.
Conditioned air for cylinder-driven case erecting, sealing and palletising stations, where a steady regulated pressure keeps clamp and pusher cylinders repeating consistently.
A 3/4 in branch line feeding a row of assembly stations, giving each bench filtered water-free air at a set working pressure from the main distribution header.
Size 600 is the largest step in the GFR range, with 3/4 in NPT ports here; step up or down through 200 / 300 / 400 / 600 to match the port and flow level of the line you are feeding. The automatic drain on this unit suits unattended duty; choose manual drain where an operator drains bowls on a schedule, or the default differential-pressure drain where the bowl dumps on a pressure drop. The 40 um element is the standard grade; specify the 5 um (W) option when finer particulate removal is needed. This code ships without a gauge, but gauge variants with MPa, psi or bar scales can be ordered, and PT, G or NPT threads are available. A bracket is included. Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request.
The A in the code specifies an automatic drain, which ejects collected condensate on its own instead of waiting for a manual dump - useful on lines that run unattended. The N specifies that no gauge is fitted; gauge variants with MPa, psi or bar scales can be ordered if you want a visual pressure reading at the unit.
